Wikipedia Meaning and Definition on 'Arrowhead'
An arrowhead is a tip, usually sharpened, added to an arrow to make it more deadly or to fulfill some special purpose. Historically arrowheads were made of stone and of organic materials; as human civilization progressed other materials were used. Arrowheads are important archaeological artifacts; they are a subclass of projectile points.
In the Stone age, people used sharpened or flintknapped stones, flakes, and chips of rock as weapons and tools. Such items remained in use throughout human civilization, with new materials used as time passed. As archaeological artifacts such objects are classed as projectile points, without specifying whether they were projected by a bow or by some other means such as throwing.
Such artifacts can be found all over the world. Those that have survived are usually made of stone, primarily being flint, obsidian, or cherts, but in many excavations bone, wooden and metal arrowheads have been found.[See more about Arrowhead at Dictionary 3.0 Encyclopedia]
